Indexing Moving Points (Extended Abstract)

Summary: External-memory indexing for N planar points moving linearly: first structure uses O(N/B) blocks and answers rectangle-at-time queries in O((N/B)^{1/2+ε}+K/B) I/Os, supports time-interval reports and O(log_{2B} N) updates. Also: an evolving-index that trades query time vs. index-update frequency for chronological queries, a scheme whose query cost is monotone in |tq−now|, and an efficient index for approximate nearest neighbors among moving points.
